White goods, chemicals, pharmaceuticals, and FMCG companies face import delays or higher duties as customs authorities scrutinize third-party invoicing at various ports. This practice, used for tax optimization, allows invoicing through a country different from the goods' origin and is permitted under FTAs. However, customs officials suspect abuse of FTA provisions, withholding consignments and denying lower duty benefits at ports like Nhava Sheva. Authorities demand differential duty payments and invoke rules addressing potential duty evasion through third-party invoicing, leading to potential supply disruptions.
